AMD quad-RX 470 prototype surfaces with 32 GB of GDDR5
A previously unseen AMD-branded board has appeared online, with four Radeon RX 470 GPUs arranged on one circuit board. The photos suggest 32 GB of GDDR5 memory in total, but AMD has not confirmed the specifications or the board’s purpose; its single HDMI output and apparent PCIe x8 interface point away from gaming.
Bottom line — The four-GPU board was never announced by AMD, and whether it was built for mining or as an engineering experiment remains unclear.
